In Office 2007 and 2010, you can go directly to Bing and search for images. You'll want to be sure that you have the rights to use the images you select, and you can do that by setting easy-to-use licensing filters. Here's how

Go to bing.com and click or tap the Images tab in the upper-left corner of the screen.

In the Search box, enter the type of image you're looking for.

When the image results appear, click or tap the License drop-down menu, and pick the licensing option you want. (If you don't see the License filter, make sure you're using a supported browser.)

In Office 2013 and 2016, you don't need to open your browser or leave your document to insert images.

Choose Insert > Online Pictures in any Office app.

Choose Bing Image Search, and type a search term in the Search box to see images from Bing.

Note: You can filter search results to CC (Creative Commons) Only (learn more here) or you can choose to see all images. If you choose All Images, your search results will expand to show all Bing images. You're responsible for respecting the rights of others' property, including copyright. To better understand the licensing options, see Filter images by license type.

Note: If you see an inappropriate image, move your mouse pointer over it, click the Report Image
icon that appears, and report the image as inappropriate.
